Automix feature simplifies mixing activities in the presence of many guests in the studio.

The function adds, to the existing sources, a new source called Automix, which is the sum of all enabled microphones.

The Automix source has all the features of a microphone source such as:

  • Studio/Control Room loudspeakers control
  • Studio/Control Room light control
  • Can be used as audio in Private mode for phone calls

Using this new source, the user can manage in a very simple manner all the microphones of the studio with a series of benefits:

  • Just 1 fader for the management of studio microphones;
  • A dedicated AGC section for each microphone input automatically adjusts the correct level;
  • Automatic management of attenuation on microphones not in use, simulating a slight closure of the fader;
  • Final compressor that allows an automatic leveling of the Automix source;
  • Possibility to use the microphones individually.

This feature further simplifies the work of the mixer engineer, even in the case he/she is also the host of the show.

Available settings in the Automix menu:

    • MIC-1    ON/OFF
    • MIC-2    ON/OFF
    • MIC-3    ON/OFF

Oxygen 2000 has two BT connection modes: bidirectional to support phone calls, monodirectional to put on air high quality stereo audio (A2DP) streamed by BT sources.

With BT calls, PFL enables PRIVATE conversation mode.

Telephone Hybrid and Telco

The built-in telephone hybrid allows direct connection of a telephone line POTS/PSTN on RJ-11C. The audio is processed via DSP that delivers a state-of-the-art audio processing. It’s also available a Telco N-1 in/out, to connect Oxygen 2000 to an external telephone hybrid. The Telco N-1 is always available on RJ45. TLC commands are available on the same RJ45 with Hook and Ring interface.

TLC commands for Telco-2-5 are available and configurable on GPIO-DB9 connector with Hook and Ring.

Software Remote Control

Oxygen Remoter is a software tool available for free with any Oxygen console. It offers advanced remote control features such as accessing to any set up and information, fader and buttons control and any  other operation available on the physical consoles. It is very useful especially for compact consoles and in any environment that has limited space.

The Virtual Fader technology enables users to assign each input to a virtual fader/channel on the remote surface, this is of course very useful when controlling channels remotely. Additionally, transforming the A/B pair into two virtual faders is a smart solution that maximizes the management of the available sources.

Oxygen Remoter can remotely control multiple consoles and create an ecosystem, this can be very helpful for remote productions where, for instance, a portion of the channels may need to be controlled from a studio while the others are still managed from the physical surface in the control room.

Oxygen Remoter is a powerful tool that provides extra flexibility and control’s tools to all the Oxygen consoles.

Oxygen Remoter is downloadable from the Oxygen console’s administration web page.

HDMI output

The HDMI output allows to connect an HD display monitor to the console, suitable to be used in two flavours:

    • Monitor, that displays the following information:
        • Audio input source levels
        • 4+1 BUS output levels
        • A/B source names assigned of 10 channels

        • The programming GUI has been designed in order to be very easy and intuitive.
        • Selectable home page layouts are available, with many theme icons.

HDMI output can be personalised with the customer logo. Selectable display layouts are available.

Talk Box

It is a device dedicated to the presenter and guests. Talk Box is very simple to connect to the On Air Console: its take 2 RJ45 cables of the length that is needed to connect it to the mixer. It is possible to connect up to 4 Talk Boxes to the Oxygen 2000. The Talk Box offers a direct connection of the microphone and relative On-Air light, it is also possible to directly connect the studio’s On-Air Light. The Talk Box has a headphone amplifier with two 6.3mm outputs. Through the two large backlit buttons it is possible to activate and deactivate your own microphone (On / Off / Cough) or enable Talk back to the console.
